CRS226 -> LACP with Windows Server 2012

RouterOS General
1

Hello!

First of all thanx for the great product. When it comes to features there is no compareable Product on the market.

My Problem:

I would like to build up a LACP connection via 2 Ports to a Windows 20012 Server containing 2 NICs.

What i did:

Using WinBox.

Starting with Default config of the switch.

My Net 10.1.1.0 /24
CRS226 IP: 10.1.1.2
Server IP: 10.1.1.111

By default all Ethernet ports are assigned to

Ether1-master-Local

and no free ports are available for Bonding.

So did set MASTER to NONE on Ethernet 21 and 22 so have some available ports for Bonding
I added a Group BONDING1 with slave ports Ether 21 an 22

Here i am stuck!

My server seems to recognise the LACP Link, but i guess the Bonded Ports have to be reassigned to the master switch to see the Rest of the traffic

Can someone give me a hint with this?

(The WIKI is assuming that 2 Routers a coupled with 2 IPs, i guess this scenario is not 100% fitting my needs?)

Thanx in advance!

Arne



P.S.

I tried bridging the bonding1 and Switch. It worked but showed very poor throughput (10-20Mbyte) using 2 1GB Ports
A single 1GB Port shows 100-120 Mbyte, so LACP is not usable to me… What did i do wrong?

I already found out that Bridging between Bonding1 and Switch can be done.

But:

The througput copying large files from the server to my machine using 2 bonded ports that are bridget to the switch is only 10-20 mbyte.
Without Bonding using a single port it is a lot faster (110mbyte).

What is going wrong?

Bonding goes through CPU so there will be a huge performance loss on the CRS.

LACP via switch chip must be done via Trunking :

OK Thanks for the quick reply.

I understood, have to add a trunk1 with my 2 ports 21/22.

Noticing that LACP is not supported till now, which kind of Teaming-Protocol on the 2012Server would be the preferred one to use?

You should use generic or static teaming on the 2012 Server to make it work with CRS Trunking.

Thanx becs for the quick support!

At last it is working now with a 2 Port trunk with 110MB maximum speed to one PC instead of the 10-20 MB before.

I hope in the near future the firmware will support LACP in hardware.

I could not find any documentation on the new QualcommAtheros 8519 chip. But i expect a chipset with 24 Ports of 1 Gbit and SPF+ Port with 10Gbit
will habe LACP hardware acceleration support. :wink:

I would estimate after a few more updates the CRS226 could be a real killer product an the Switch Market
